Conventional subwoofers use a large ferrite motor mounted to the back of the basket.  This makes shallow mounting extremely difficult.   By using a neodymium motor, which is capable of creating the same magnetic force as a traditional ferrite motor, but at a fraction of the size, and mounting it in front of a woven carbon fiber cone, depth is no longer an issue.   And since we are not squashing the entire subwoofer in an effort to improve the mounting depth, we don’t sacrifice the geometry of the driver and therefore maintain the same type of performance you would expect from Diamond Audio.
